Show answer & explanation
Correct answer: D
To determine the sum of the first and second number, we can break the problem into clear, logical steps.
Step-by-Step Analysis
Find the Second Number:
The problem states the second number is 12% of 100.
Calculation: 0.12 × 100 = 12.
Find the First Number:
The problem states that two-thirds of the first number is equal to the cube of the second number.
First, find the cube of the second number (12): 12 × 12 × 12 = 1728.
Let the first number be x. The relationship is: (2/3)x = 1728.
To solve for x, multiply both sides by (3/2): x = 1728 × (3/2) = 864 × 3 = 2592.
Find the Sum:
Add the first number (2592) and the second number (12).
Sum = 2592 + 12 = 2604.
Correct Option
Option D: 2604
